In the process of performing roofing work, as well as when repairing the roof, waterproofing material is laid or bituminous mastics are melted, for which a propane burner is used. In addition, it can also be used for drying surfaces, cutting or soldering metals, heating any blanks or products to high temperatures, burning old paint and other jobs that require these conditions.
Usually a propane burner is a metal cup, which is equipped with a nozzle and a plastic (or wooden) handle fastened to the body. The glass of the device is designed in such a way as to protect the flame from being blown out by the wind. Gas enters the housing through a gas pipeline. The propane burner is equipped with a valve that makes it easy to adjust the gas supply in the right amount. Flame length is also adjustable. Saving propane is achieved due to the fact that the device is equipped with a reducer that controls its consumption. Almost all types of burners are capable of sucking air from the atmosphere. The device is launched using a lighter or matches.
The propane burner is equipped with a device that helps regulate operating modes. Many models have a standby mode, which allows you not to waste gas in vain during a break in work. During operation, the device is heated to very high temperatures, which forces the manufacturer to use only high-strength materials for the manufacture of these products. The propane roofing burner is equipped with a handle, the length of which is no more than a meter. The weight of the entire device is 1-1.5 kilograms. Protection against burns is provided by the presence of a holder made of heat-resistant plastic or high-strength wood.
There are certain rules for working with a device such as a propane gas burner. If roofing material or some other modern material for built-up roofing is used as a waterproofing material, then you should first prepare the base for its laying. To do this, the base must be cleaned of debris, and then leveled with a concrete screed, if necessary. The rolled material is rolled out over the entire area of the roof so that adjacent sheets form an overlap, the width of which is up to 90 millimeters. Using a burner, the rolls are fixed at the base of the roof. When the flame warms up this base and the bottom of the roll, you can slowly roll outmaterial, then to press it to the base. Further along the canvas, you should run a hand roller to get rid of all air gaps.
The last step in using the torch involves heating the seams of the material that are overlapped. The seams should be additionally rolled with a special hand tool. The use of a gas burner for work is allowed only at temperatures above 15 degrees below zero. Lower temperatures force the use of liquid fuel appliances.
